Abstract

Transparent blue crystals of Cu[N(CN)(2)](2) center dot 2 NH3 were obtained by blending solutions of Na[N(CN)(2)] and Cu(NO3)(2) center dot 2.5 H2O in aqueous ammonia and subsequent evaporation of the solvent under ambient conditions. Cu[N(CN)(2)](2) center dot 2 NH3 crystallizes in space group P (1) over bar (no. 2, Z = 2) with the cell parameters a = 746.1(4), b = 747.8(4) and c = 894.4(5) pm, and the angles alpha = 68.94(2), beta = 75.52(1) and gamma = 68.22(4)degrees. The presence of the dicyanamide anion and the ammonia molecules was verified by Raman spectroscopy.
